What were ancient Sparta's goals?

this is a very vague question for two parts: Which acient Sparta? Sparta changed and evovled most drastically under the reforms of Lycorgous. however for the purpose of answering the question I'll assume you are reffering to the most well known period of spartan society in the 6th and 5th centuries BC. and also, goals in relation to what? to foreign policy, mlitary expansion, cultural and society?

well in general the Spartans goals were to create an invincible land force, which they needed to keep the helots (messenian slaves) which outnumbered them 10 to 1, from revolting (which happened on many occasions, most famosly Mt Ithamae). they were always very relutant in moving out of the peloponesse, so their goal ws to reamin as strong as possible, and not t have to leave the pelopponese often.
